United States Patent WAVE OPERATED PUMPING MECHANISM Ayoub Shumen, Paterson, N. J. Application November 5, 1956, Serial No. 623,271 1 Claim. (Cl. 103-70) This invention relates to a wave operated pump.

One of the objects of the invention is to provide a simple waved operated pump which is stable in ocean water.

The drawings show one form of the invention, as required, and in these:

Fig. 1 is a perspective view of the upper part of the apparatus, the lower part being submerged;

Fig. 2 is a plan view of the apparatus;

Fig. 3 is a vertical section of Fig. 2, on broken line 3-3 of Fig. 2;

Fig. 4 is a horizontal section on line 4-4 of Fig. 3;

Fig. 5 is a broken perspective view of a ball bearing track employed in the apparatus; and

Fig. 6 is a horizontal section on line 66 of Fig. 3.

Referring to the drawings for a more detailed description thereof, the apparatus comprises a stationary structure, to be securely anchored, and a float, rising and falling with the waves, and connected to pumping mechanism, the rise and fall of the float providing the power. The stationary structure comprises four triangular columns 8, radially disposed, to be adequately anchored to the ground on a supporting structure, and a deck or platform 10, secured to the upper end portions of the columns in any suitable manner, as by plates 11 (Figs. 2 and'4). It will also be seen that the platform has triangular projections 14 fitting into corresponding recesses of the triangular columns 8 (Figs. 2 and 4).

A round hollow float 15 rides up and down with the rise and fall of the waves, guided by the columns 8. As shown in Figs. 3 and 6, the float has triangular projections 17, fitting into corresponding recesses in columns 8 and each contacting two sets of ball bearings 19, the latter held in vertical ball bearing races at right angles to each other and shown in Fig. 5 as embedded in columns 8. The float 15 has a vertical tube 21 passing ice centrally therethru, and through tube 21 passes a tube 22 secured thereto. Tube 22 extends from the bottom of the float upwardly through the center of the platform 10 and a little thereabove and has an upwardly opening valve 25 at its upper end. The upper portion of tube 22 lies Within a tube 26 which extends centrally through and is secured to the platform 10. Tube 26 has a spherical member 27 at its upper end and acts as a reservoir. As appears in Fig. 3," a tube 28, opening into spherical member 27, extends to the left thereof, and has a valve 30 which opens to the left when pressure is exerted on its right. When float 15 falls, water rises in tube 22, above valve 25, opening the latter and entering into the space above the valve 25, which space is that of tube 26 and of spherical member 27. When the float rises, tube 22 pumps the water lying above valve 25 thru the valve 30 of tube 28.

What is claimed is:

Wave-operated pumping apparatus consisting of a hollow circular float adapted to rise and fall with ocean waves, four anchored vertical guides for said float, a platform secured to the upper ends of said guides, a first vertical pipe secured to the float and extending upwardly from the center of the bottom of said float and through the same to a point thereabove, and terminating at the bottom of the float, said first pipe open at the bottom to receive water from the Waves and adapted to rise and fall with the float, an upwardly opening valve at the top of said first pipe, a second vertical pipe secured to the platform and disposed around the upper part of the first pipe, a reservoir at the top of the second pipe and connected thereto, a third pipe connected to and leading away from said reservoir, an outwardly opening valve in said third pipe to allow water to pass therethrough when the float rises, said anchored vertical guides being triangular and radially disposed, with vertices outermost, said float having triangular projections fitting into corresponding vertical recesses in said guides, a pair of ballbearing sets at right angles to each other in the recess of each guide, against which sets bear the mentioned triangular projections of said float, said sets including T-shaped frames for the ball bearings.
